C3-Predictor: An Efficient Framework for Performance Prediction of Concurrent Queries

Query performance prediction is a challenging task in AI-enabled database (DB) research because prediction capability is crucial to optimizing DB operations (e.g., parameter optimization) and resource allocation in modern DB systems. However, existing methods often struggle to meet the flexible requirements for both pr...

Label Distribution Enhancement-Based Label Completion for High-Noise-Ratio Crowdsourcing

Label completion serves as a preprocessing step to handle the sparse crowdsourced label matrix problem, significantly boosting the effectiveness of the downstream label integration. However, existing label completion algorithms generally focus on the crowdsourcing scenarios with low noise ratios but rarely focus on the...
